+Blackbox exporter is configured via a [configuration file](CONFIGURATION.md) and command-line flags (such as what configuration file to load, what port to listen on, and the logging format and level).
 
 Blackbox exporter can reload its configuration file at runtime. If the new configuration is not well-formed, the changes will not be applied.
 A configuration reload is triggered by sending a `SIGHUP` to the Blackbox exporter process or by sending a HTTP POST request to the `/-/reload` endpoint.
 
 To view all available command-line flags, run `./blackbox_exporter -h`.
 
-To specify which configuration file to load, use the `-config.file` flag.
